Subject: [PATCH 1/2] ASoC: fsl: sai: Add support for runtime pm
Date: Sat, 20 Apr 2019 15:59:04 +0000 [thread overview]
Message-ID: <20190420155846.10027-2-daniel.baluta@nxp.com> (raw)
In-Reply-To: <20190420155846.10027-1-daniel.baluta@nxp.com>
Basically the same actions as for system PM, so make use
of pm_runtime_force_suspend/pm_runtime_force_resume.
